Hey- I have Comcast cable internet connected to my computer (it works) and the Vontage Motorola VT 2142 connected to the cable modem. (it also works with my phone.) The trouble I am having is that my husband has a handheld device for work, and the issued him a Apple Airport Extreme to use to send the data from the handheld. We connected the Apple just like the instructions his work gave him...power cord into the wall, and phone line into the Vontage router...but his handheld will not transmit. It's saying that it's connected, but won't transmit. It does transmit from his co-worker's home, who also has cable internet and a Vontage phone. We have tried turning the bandwidth down to low, restarting/unplugging, and Vontage tech support even had us move some wires around...but no luck. Does anyone have any clue why this will work from someone else's house and not ours? I would be grateful for any ideas...
